Application June 21, 1937, Serial No. 149,284

1 Claim.

The present invention relates particularly to means for closing off the space that ordinarily exists between the bottom of a door, when closed, and the underlying sill.-

It is one object of the present invention to provide means-of the character indicated operative to automatically close the passage referred to when the door is closed, and be automatically raised out of contact with the floor when the door is opened.

It is another object -.of the invention to provide means of the character indicated that may be applied to a door without the necessity of making structural changes therein.

It is a further object of the invention to provide means of the character indicated that may be applied by unskilled labor; that consists of few parts; that is simple in form and construction; that is economical to manufacture; and that is strong, durable, and highly efficient in its practical application.

In the drawing:

Figure 1 is a plan view of a door fitted with a device embodying our invention, a part being 25 broken away.

Figure 2 is a perspective view of a portion of the bottom edge of a door with a device embodying the invention in position thereon, with parts broken away.

Figure 3 is a perspectiveview of a portion of a door frame and sill showing the operating cam in position.

Figure 4 is a sectional view on line 4-4 of Figure 1, greatly enlarged.

Referring now more particularly to the drawing, we show at l a door hingedly mounted as at 2 in the frame 3, the door stop being shown at 4.

In the present instance we show at 5 a long narrow strip of sheet metal, somewhat narrower 40 than the door itself and extending substantially the full length thereof.

One of the longer sides of the strip 5 is bent around a rod 6 to swing freely thereon. The rod 6 is bent at right angles at each end and seated in the bottom of the door as at l. A small section of the end of the strip adjacent the free end of the door is bent downwardly a little as indicated at 8 to form a cam surface 9 for the purpose hereinafter described. On the 50 bottom of the strip 5 and extending practically its'full length is a strip of felt as at H].

At H is shown a resilient rod having one end bent at right angles to seat in the bottom of the door as at I2, the other end being bent at right angles to the rod and disposed at an angle of ninety degrees to the end 12 to overlie the bottom of the felt l0 and strip 5 as at I3. In the present case the rod H is held in place by 5 means of staples as at M.

Seated in the jamb l5 of frame 3 and near the bottom thereof adjacent the stop 4 is a small metal tab Hi. This tab is disposed at an angle to the sill I! to form a cam surface I 8 engage- 10 able with the cam surface of the part 8.

The result of this construction is that when the door is open the spring rod ll urges the strip 5 upwardly against the bottom of the door so that the door will swing freely without the strip rubbing on the carpet, or rug over which it moves. But when the door is closed the cam surface 9 on part 8 engages the cam surface l8 on tab l6 and forces the strip downwardly about its pivotal mounting 6 and causes its free 20 edge to engage the sill and thereby completely close the opening l9 between the door and sill.

It is to be understood, of course, that while we have herein shown and described but one specific example of our invention, changes in form, construction, and method of assembly and operation may be made within the scope of the appended claim.

We claim:

A device of the character indicated comprising, 80 the combination with a hinged door and its frame of a rod having its ends bent at right angles and seated in the bottom edge of the door adjacent each end thereof and adjacent one of its longer edges, a strip of sheet metal narrower than the bottom of the door having one longer edge bent around said rod to swing thereon and extending the length thereof, the end portion of the strip being bent downwardly on its free edge to form a cam surface, a metal tab driven into the side of the door frame and disposed at an angle to the bottom of the door frame to form a cam surface adapted to engage the cam surface of the strip and force the free edge of said strip downwardly when moved into engagement therewith, and a resilient device mounted on the bottom of the door to engage the strip to urge it upwardly to lie flat against the bottom of the door when the cam surfaces are not engaged,
